Testify that go "Who controls the past now, controls the future / Who controls the present now controls the past"? (And then it rocks your face off!) Yeah, those are direct quotes from Orwell's 1984. And the line in the Muse song Resistance that goes "Kill the prayers for love and peace / you'll wake the thought police"? Obviously "thought police" is another 1984 reference. Radiohead wrote a song titled 2+2=5 and the Incubus song Talk Show On Mute invites us to "come one, come all into 1984."
And those references are just off the top of my head — which, I'm sure, means the above is just the tip of the iceberg in terms of references to the novel 1984 in music specifically, but also in general pop culture. (Just so we're clear, I'm not even mentioning the idiotic show Big Brother.)
It's a pretty influential novel (...states Captain Obvious). If you've never read it, give it a try. It's not nearly the slog some "classics" are. There are slower parts where there's no "action," per se, but if you're like me, and you're interested in politics and philosophy and the philosophy of politics, even the slow parts are fascinating.
One example: Orwell spends 30 pages showing us Winston Smith reading a book about the counterarguments to the Party's ruling philosophies (Ingsoc, or English Socialism) and slogans (i.e., War is Peace). It takes some brain work, but unpacking the arguments is rewarding. So is reading the epilogue in which Orwell describes Newspeak — the invented language of the Party that reduces the number of words in order to reduce critical thinking and opposition to the Party.
And you get to learn about solipsism — which, if you don't remember your Phil 101 course, is the notion that reality exists only in the mind. So once you get that, then you can sound smart at cocktail parties by saying things like, "You know, Greg seems like a reasonably intelligent person, but his solipsistic views and the fact that he rejects the objective nature of reality, make me want to brain him with blunt object."
Finally, here's this: A little tongue-in-cheek thought experiment on Book Riot to determine which was better, Orwell's 1984 or real 1984.
So, what other 1984 pop culture references have you noticed?
